 Abstract

In this paper an image resolution enhancement technique which generates sharper high resolution image is proposed. The proposed technique uses DWT to decompose a low resolution image into different sub-bands. Then the three high frequency sub-band images have been interpolated using bi-cubic interpolation. The high frequency sub-bands obtained by SWT of the input image are being incremented into the interpolated high frequency sub-bands in order to correct the estimated coefficients. In parallel, the input image is also interpolated separately. Finally, corrected interpolated high frequency sub-bands and interpolated input image are combined by using inverse DWT (IDWT) to achieve a high resolution output image. The proposed technique has been compared with conventional and standard interpolation techniques, wavelet zero padding (WZP), where the unknown coefficients in high-frequency sub bands are replaced with zeros, state-of-art techniques. The performance of the proposed technique over performs all available state-of-art methods for image resolution enhancement. In all steps of the proposed satellite image resolution enhancement technique, Daubechies wavelet transform as mother wavelet function and bi-cubic interpolation as interpolation technique have been used.

Steganography is nothing but study of invisible communication. Steganography is method of hiding communicated data .secresy is achived by embedding data into image . There are different types of steganography techniques. In this paper we review these methods with its strength and weaknesses.

Any person can gain access of his workplace personal data anytime at anywhere because of 5G network and cloud technology. The most appropriate way for us to access to cloud data is to use personal smart phone. On the other hand, Because of low security protection and limited computation resource, smart phone is somewhat vulnerable while facing with malicious attacks in open network. Attacker can penetrate to different levels of cloud as well as to infrastructure of mobile to steal and temper data, which may prone to new type of attack - advanced persistent threat (APT). This survey paper insights security and privacy risk of mobile cloud in the perspective of applied cryptography and also provides solutions for the risks.

ABSTRACT: Urban Centre is always being an attraction of surrounding people. Industrialization and urbanization have resulted in a large number of migrations from rural areas towards the city for large employment opportunities to improve the living standard. Coimbatore city is one of the second biggest urban centre after Chennai city in Tamilnadu, The city were which has more agriculture land open land, wasteland, and dry land categories changing into urban aspect like residential and industrial and |Educational categories. The selected study area is Coimbatore Corporation. In this paper analyzed the land use changes for the two period of 1981 and 2011.Data collected from LPA (Local Planning Authority) and simple statistical calculation were made to find out the changes in land use pattern, The Arc Gis 10.3 Software were used for preparing the maps and representing different categories of land utilization of urban centre. The major findings of the study are more agricultural land is converted in to residential, educational and industrial uses so on.

 Abstract

Digital communications can perform unreliably and inaccurately in the presence of noise and interference along a channel. A technique has been developed not only to detect these inaccuracies, but also correct them when decoded. Here we are implementing a block coded system consisting of Reed Muller (RM) code for error detection and correction. RM codes are a family of linear error-correcting codes used in communications. RM codes are among the oldest known codes and have found widespread applications. A useful log domain belief propagation algorithm is used for decoding purpose. The algorithm works by passing real valued functions called messages along the edges between the bit node and check nodes. The performance will be evaluated and validated under Additive White Gaussian Noise channel environment (AWGN). A MATLAB simulation results were tested to achieve bit error rate of 10-5. Simulations are carried out with variable code rate and with 10 iterations. It is observed that bit error rate performance of system depends on code rate, block length and number of iterations.

 Abstract

The present paper deals with the microwave assisted synthesis and screening of antimicrobial activity of Schiff base derivative of 2- Amino benzimidazole and their cobalt complex. The synthesized ligand, and their cobalt complex were screened for their antimicrobial and antifungal activity. Schiff base metal complexes are an area of increasing interest. These complexes have numerous applications, such as, in the treatment of cancer, as antibactericide agents, as antivirus agents, as fungicide agents and for other biological properties. Benzimidazoles are very useful intermediates/subunits for the development of molecules of pharmaceutical or biological interest. In the present study Schiff base of Co(II) complexes synthesized from the Schiff base Ligand. And the Schiff base ligand 1-(anthracen-9-yl)-N-(1H-benzimidazol-2-yl )methanimine synthesized by the reaction between 2-amino benzimidazole with 9-anthracenecarboxaldehyde under microwave irradiation .The synthesized compounds were purified by recrystallisation and Further, compounds screened for antimicrobial activity against Escherichia coli (NCIM 2256), Staphylococcus aureus (NCIM 2079) , Pseudomonas aeruginosa (NCIM 2257), Klebsiella pneumoniae (NCIM 5432), Candida albicans (ATCC 10231)and Streptococcus pneumoniae (ATCC 49619).

 Abstract

Due to the high cost of time several methods are proposed to reduce the wastage of time on the bus station or waiting for the bus for more time is not preferred. So, we require one racking system to track the Complete Transport System. Every GPS tracking system is a common approach to get vehicle location information in real-time. We proposed a GPS tracking system called tRackIt that is composed of commodity hardware i.e. GPS enabled Android Mobile as GPS Device , open source software(GCM Architecture) and an easy-to-manage user interface via a web server with Google Map software. The system includes a GPS/GPRS module for location acquisition and message transmission, GCM to transfer of location information, and third party App Server to temporary store location. Our proposed system is not tested yet. But it will show the correct position of the vehicle to the user on the basis of the location information sent by the GPS Device through GCM.
